Slim Node.js HTTP Server

Installation

• Install the npm package npm install slim-node-server
• Import the module to your project (see example below)

Usage

After installing installing the framework, create a new instance of Slim and start creating your server:

// import slim framework
const Slim = require('slim-node-server');

// create new slim server with logging
let app = new Slim(true);

app
    .get('/', (req, res) => {
        res.end('nothing here yet');
    })
    .get('/some-json', (req, res) => {
        res.json({ task: 'Task 1' });
    })
    .listen(8080, '0.0.0.0', () => {
        console.log('Listening');
    });

Middleware

• All request types support middleware functions
• The last function must end the response
• All route handler functions are executed in the order they are specified

Example:

function log(req, res, next) {
    console.log('LOG VISIT', req.url);
    next();
}

// add middleware to log page url visited to server console
app.get('/', log, (req, res) => {
    res.end('Visit has been logged');
});

Query Parameters

Parse query parameters as needed using the request object in a handler function. Example:

app.get('/echo-name', (req, res) => {
    const queryParams = req.query();
    res.end(queryParams.name);
})

Body Parsing

Parse a payload body as needed using the request object in a handler function. Example:

app.post('/', async (req, res) => {
    // wait for all payload data to parse
    const payload = await req.body();

    // echo back the payload to the client
    res.json(payload);
})

Router

Routes can be imported from other files to reduce file size. Example:

app
    .addRoutes('/api', require('./routes/'))
    .listen(8080, '0.0.0.0', () => console.log('Server listening'));
